SPECIFICATION forming part of Letters Patent No. 297,763, dated April 29, 1884.

(No model.)

To all whom it may concern;

Be it known that I, JOHN M. CASE, a citizen of the United States, residing at Columbus, in the State of Ohio, have invented a new and Improved Disintegrating and Separating Machine for the Manufacture of Flour and Middlings, of which the following is a specification.

My invention has for its object the production of a complete and successful disintegrating andseparating machinefor use in gradualreduction milling. l

All improvements in the modern art of milling tend in one direction-that is, to separate the interior or flour-producin g part of the bran without incorporating therewith the particles of bran, germ, and other impurities which discolor the flour. l 1

My new and improved disintegrating and separating machine is constructed with a reel made of longitudinal bars or beaters and a casing, within which the said reel is revolved at a high velocity, the casing being provided with a number of inwardlyprojecting studs, against which the material is thrown by the rotation of the reel with forcible percussive action, and with screens through which the material will pass when sufficiently comminuted. \Vhile the machine may be made to effect a complete and perfect separation of the bran from the interior of the wheat-berry, yet this action is greatly facilitated by using the machine in combination with crushing-rolls. It may be used as well in the reduction of middlings to flour as in the reduction of wheat to middlings,as it combines the principles of reduction by percussive action with a sifting arrangement, whereby the particles reduced are discharged as soon as they are reduced to rounds the beaters.

In the accompanyingdrawings, Figure I is a vertical transverse section of the improved machine. Fig. II is a vertical longitudinal section of the same.

By reference to Fig. I it will be seen that I construct a casing made up of concaves 1 2 at top and bottom, connected by wire-cloth 3 4 thrown into motion by beaters on a cylinder revolving within the casing. cylinder consists of two metallic heads, 6, fastened'to the shaft 7, and rods or beaters 8, reaching from one head to the other. For these rods I preferably use steel wire about onefonrth ofan inch in diameter. These wires are strained tightly between the metallic heads. The cylinder is caused to revolve with a very rapid.motion-from two to three thousand per minuteor it may be faster or slower. This rapid rotation of the beaters 8 throws the material with great force against the wirecloth 3 on the ascending side. Then, rebounding from the cloth, it is caught by the beaters The revolving and thrown against the projecting percussionpoints 5,. and then against the opposite wire screen 4. In this severe action the flour-making material adhering to the bran is forced off, and as soon as reduced to the proper size passes through the wire-cloth 3 4., and is taken off by means of the delivering-hopper 9 and conveyer 10 and dischargespout 11 contained in an outer box or casing, 12; or a simple delivery-hopper may be used.

A feed-spout is shown at 13 and a tailings spout at 14, to carry off bran and other material too large to pass through the screens. These materials may be separated by blast or other well-known means, and the heavy parts returned through the feed-spout 13, for rebeating, or taken to suitable breaking devices. It will be seen by this means of reducing wheat no cutting or grinding surfaces are used, and consequently there can be no abrasion of the bran or incorporation of coloringmatter with the flour.

When this machine is used in connection with crushing-rolls, the wheat can be reduced 0 to middlings and the bran discharged perfectly clean in three operations of crushing and whipping.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

and a beater-cylinder mounted and revolving ecoentrically therein, as and for the purpose 1:) set forth.

JOHN M. CASE.
